Ludwig-Maximilians-Universitaet (LMU) in Munich researchers have used CRISPR technology to probe the mechanisms that guide the developmental trajectories of stem cells in the brain. The results show that crucial cellular ...

The complex inner workings of cells, from their architecture to their signaling, underlie much of multicellular organic life. How are they built? How do their proteins interact? And most crucially, how can understanding these ...

Many viruses, including that perennial winter affliction, the influenza virus, are protected by a lipid membrane on loan from the host cell. The fusion proteins on the surface of the membrane are tasked with merging the lipid ...

For the first time ever, scientists have imaged the process by which an individual immune system molecule is switched on in response to a signal from the environment, leading to the critical discovery that the activation ...

The Argonaute (Ago) enzyme complex plays a critical role in DNA and RNA target cleavage for a process known as RNA silencing in prokaryotic and eukaryotic cells, making them a target for future gene-editing technology. The ...

To perform the task for which they have been synthesized, proteins must first assemble to form effective cellular "machines." But how do they recognize their partners at the right time? Researchers at the University of Geneva ...

Forty-two years after Carl Woese defined archaea as the third domain of life, scientists at the Carl R. Woese Institute for Genomic Biology (IGB) at the University of Illinois at Urbana-Champaign are still learning about ...

Why do distinct species have different proteins? Is there a key that allows eukaryotic cells to produce proteins involved in multicellularity that are mostly absent in prokaryotes? These are some of the questions addressed ...

From kryptonite for Superman to plant toxins for poison ivy, chemical reactions within the body's cells can be transformative. And, when it comes to transmuting cells, UC San Diego researchers are becoming superhero-like ...
